The building will be steel framed, like the Cactus Tower, but with facades composed of a grid of vertical and horizontal louvers with in-fill glass panels. As the tower curves more steeply, the louvers will move closer together. The louvers separate as the curve flattens.
The internal structure will be made up of a series of straight pipes about 18-inches in diameter. The pipes will be segmented again and again, following the curvature of the building’s exterior. “The biggest challenge was how to make the columns,” said Moss. “The shapes are complex and if you miss by a little bit, the closer you get to the ground, the more precarious the dimensioning discussion.”
